摘　　要：基于Luenberger最小阶状态观测器的设计,给出了一类奇异系统(或称广义系统、描述变量系统、代数微分系统、不明确系统等)观测器的参数化表示及其状态空间实现。引入了一个附加的真稳定的有理矩阵,以保证观测器的参数化因子都是真稳定的。最后明确揭示了观测器参数化的结构机理。所得结果可用于奇异系统鲁棒观测器的设计及故障检测。Using a Luenberger' s minimal-order state observer and an auxiliary stable matrix, a new parameterization of all causal observers is addressed for singular systems (or called generalized dynamical systems, descriptor systems, algebraic differential systems, and implicit systems). The state-space realization of the parameterization is derived, and the system structure and the mechanism of the parameterization are also analyzed explicitly. The presented parameterization will be useful in some control applications such as robust observer design and fault detection.
